Single Sign-On (SSO) is a user authentication process that allows individuals to access multiple applications or services with just one set of login credentials. Instead of remembering different usernames and passwords for each service, users can log in once and gain access to all connected platforms. This simplifies the user experience and enhances security by reducing the chances of password fatigue. With SSO, organizations can manage user access more efficiently. For example, when an employee leaves a company, IT can easily revoke access to all applications linked to that employee's account. This streamlined approach not only saves time but also helps protect sensitive information across systems like Google Workspace, Microsoft 365, and Salesforce.
